JOHN F. STRATTON, OF BROOKLYN, NEW YORK.

MOUTH-HARMONICA.

SPECIFICATION forming part of Letters Patent No. 364,610, dated June 7,1887.

Application filed February 11, 1887. Serial No. 227,3l7. (No model.)

To all whom it may concern:

Be it known that 1, JOHN F. STRATTON, of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Double-Reed Mouth-Harmonica, of which the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved double-reed mouth-har- .monica which has a rich and harmonic tune when played, forming a duet.

Theinvention consists ofa mouthharmonica provided with an upper set of reeds, of which each reed forms with the corresponding reed of the lower set of reeds a chord.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a perspective view of my improvement with parts broken out. Fig. 2 is a cross-section of the same, and Fig. 3 represents a diagram of the notes of the reeds.

Double-reed mouth-harmonicas as heretofore constructed were provided with upper and lower sets of reeds; of which acorresponding set of upper and lower reeds represented the same note in octavesthat is, the upper set of reeds was tuned an octave higher than the lower set, or vice versa. The correspond iug upper and lower sets of reeds are usually played simultaneously,and produce a monotonous sound. In my improved mouth-harmonica, presently to be described, I obviate this monotony.

The mouth-harmonica A is providedwith the upper sets of reeds, B B B B &c., and with the lower sets of reeds, O O O 0, &c. The construction of the reeds and the other parts of the mouth-harmonica are the same as in the mouth-harmonicas now used, and I do not claim any special construction thereof.

.heretofore constructed.

The corresponding reeds B and O or B and G or B and instead of being tuned to the same note in octaves, as is nowdone, are tuned to different notes. The two notes selected for a corresponding set of upper and lower reeds, B and O or Hand 0, &c. ,form a chord, thus producing, when played together, a harmonious, rich sound which could only be produced by two performers on two mouth-harmonicas as For instance, in the diagram shown in Fig. 3 the upper notes 0, D, E, G, G,.B, O, D, E, F, G, A, B, G, D, E, F, G, A, O correspond to the upper reeds B B B B 820.. while the notes E, G, G, D, E, G, E, G, O, D, E, F, G, E, G, G, D, E, F, 0 correspond to the lower reeds G O O G, *0. Thus the notes 0 and E, D G, E G, G'D G E BG,OE,DG,EG,FD,GE,AF BG OE, D G, EO, F D, GE, A F, OOformcorrespondingset-s of upper and lower reeds, each set making a chord.

My improved mouth-harmonica is played in the same manner as the mouth-harmonieas now in general use.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. In a double recd mouth harmonica, the upper set of reeds, in combination with the lower set of reeds, of which each reed forms with the corresponding reed of the upper set of reeds a chord, substantially as set forth.

2. As a new artiele'of manufacture, a double-reed mouth-harmonica having each reed of the upper set of reeds so tuned as to form with the corresponding reed of the lower set of reeds a chord, substantially as set forth.
